Abstract: ABSTRACT          The invention relates to a video compression method to be employed in connection with the conditional replenishment transmission and receiving method. In the transmitter there are detected such areas of the image that are changed with respect to the previous image, and the picture information representing the occurred changes, along with the addresses of the respective picture areas,  is sent into the trans-mission channel. In the receiver there is reconstructed the new  image  on  the  basis  of  the  previous  image and  the picture  information  representing  the  occurred  changes. According to the invention, both in the transmitter and the receiver there is employed at least one reference memory (6;  14)  whereinto  a  reference  image  of  the  transmitted picture information is stored and which reference memory is used so that whenever the transmitter recognizes a picture area  to have  changed,  it  is checked whether the changed picture information corresponds to the information stored in the respective location in the reference memory; if the answer is positive, the transmitter sends a code word in-forming the receiver that the required picture information must be picked from the reference memory; if the answer is negative, the picture information representing the changes occurred in the picture area is transmitted.

It consists of a belt idler pulley jour-nalled for rotation upon the distal end of a mounting arm which in turn is secured for selective rotation by the other end thereof to a mounting bracket.  A spring loaded actuating arm rotates the mounting arm through an arc from a belt  tensioned position to a belt untensioned position and vice versa and the actuating arm may be selectively held  in the belt tensioned position.   An adjustment is provided between the actuating arm and the mounting arm to preset the angle therebetween and thus the relationship of the pulley with the belt.  The inner end of the mounting arm and upper end of the actuating arm are mounted on a center line between the upper and lower runs of the belt so that the device can be adjusted to engage the outer surface of either of the belt runs depending upon drive direction.

Abstract: Abstract A method and device for indicating the swelling of a casing or the like having a wall with at least one generally planar portion prone to deformation by pressure buildup within the casing.  The device comprises an elongate strip of visible frangible material adapted for spanning superposition with the planar portion of the wall and means for securing opposing ends of the frangible strip to the casing to restrict movement of the ends perpendicular to the planar portion of the wall. Increasing bulging of the wall deflects the frangible strip to the point of fracture thereof.  In another embodiment, gaskets may be interposed between the ends of the frangible strip and the wall of the casing to provide a clearance therebetween, thus increasing the permissible degree of bulging of the wall which may occur before deflection of the frangible strip.  The method comprises superposing the device in spanning relation with a planar portion of a wall of the casing and securing opposing ends of the frangible strip to the casing to restrict movement thereof perpendicular to the planar portion of the wall.

Abstract: Ice-cream confectionery or similar food products with relief-patterned surface manufactured by extruding ice- cream or an equivalent material from a rotary extrusion nozzle, the cross section of which has an asymmetrical shape in relation to the axis of rotation. The extruded material is fed from the nozzle directly into an undefined area and is arranged on a conveyor belt, which is not involved in the rotation of the extrusion nozzle. An elongated spiral extrusion product is thereby deposited on the conveyor belt, the outside of which product has relief patterns with projecting rope or band- like sections 15, 16, possibly in different colours. By modifying the shape of the nozzle on the apparatus and/or by having the extruded mass perform oscillatory movements whilst deposited on the conveyor belt, a rich variation of the relief patterns can be produced. <IMAGE>

Abstract: A targeted or controlled medicament liberation system which has specificity for hepatobiliary receptors, which are the specialised metabolic cells in the liver. This system is described below as being a hepatocyte-directed vesicle or HDV for short. This preferred, directed liberation system uses a bipolar lipid for the major part of the vesicle membrane structure. The homing substance, which only constitutes a relatively small part of a targeted vesicle system, possesses a specificity for hepatobiliary receptors in the liver. The heptocyte- directed vesicle is then attracted by the receptor and the vesicle liberates its contents of pharmacological material. The homing substance or molecule is preferably attached to the vesicle by first of all providing a linker or connector molecule, of which one part is embedded in the vesicle wall, since it is lipophilic, and one part, which is hydrophilic, projects or protrudes from the vesicle wall. The targeting and connector molecules are linked together so as to extend the target molecule at a distance from the vesicle wall. All chemical compounds which can circulate in the bloodstream of humans or homeothermic animals and which are attracted by hepatobiliary receptors can be used as a target substance in the invention. <IMAGE>

Abstract: A gaseous stream comprising nitrogen and solvent vapor istaken from a curing oven (not shown), is passed through preliminary heat exchangers 13 and 23, and enters a first heat exchanger 33 through conduit 30. Remaining vapor is condensed in the heat exchanger 33 by heat exchange with chilled medium entering the heat exchanger from conduit 52 and leaving via conduit 37. The medium then enters a second heat exchanger 43 via conduit 42 where it is chilled by liquid nitrogen supplied via conduit 47, the chilled medium being recycled to the first heat exchanger. The resulting vaporised nitrogen is supplied to form gas curtains at the entrance and/or exit of the oven. This nitrogen leaving the first heat exchanger 33 is used to supply a return stream to the interior of the oven at a rate that substantially matches that at which nitrogen is withdrawn from the oven. This enables a mass balance to be maintained in the oven atmosphere.
